CBSE Class 10 Syllabus 2027: Subject-wise Preparation Tips
With theory board exams in February–March 2027, you have approximately four to five months from October 2026 to cover the full syllabus and revise. Use the subject-wise tips below to plan your preparation.
Mathematics
- Algebra (Unit II) carries 20 marks — prioritize it above all other units. Cover Quadratic Equations, Pair of Linear Equations, and Arithmetic Progressions before moving to other units.
- Complete every NCERT exercise question; skip none. Board questions closely follow NCERT examples and exercise problems.
- Revise Geometry (Triangles and Circles) systematically — proof-based questions of 4–5 marks appear every year.
- Attempt at least three full-length CBSE sample papers under timed conditions before January 2027.
- If you choose Mathematics Standard (Code 041), supplement NCERT with R.D. Sharma’s exercises for higher-difficulty practice.
Science
- Chemical Substances and World of Living each carry 25 marks — together they account for 62.5% of the theory paper.
- Read every NCERT in-text question and chapter-end question carefully. Board questions are drawn directly from them.
- Draw and label diagrams regularly — Electric circuits, the Human Eye, the Digestive System, and Mendel’s cross diagrams appear in 2–3 mark questions every year.
- Complete all prescribed practical experiments before the internal assessment in January 2027. Practical marks are straightforward to secure.
- Skip the three deleted chapters entirely: Periodic Classification of Elements, Sustainable Management of Natural Resources, and Sources of Energy.
Social Science
- All four disciplines carry equal marks — History, Geography, Political Science, and Economics each contribute 20 marks to the theory paper.
- Practice map marking for Geography every week. Map-based questions on minerals, industries, and transport appear in every board paper.
- Write answers in structured bullet points for History and Political Science. Long narrative answers lose marks for poor organization.
- Consumer Rights (Economics Chapter 5) frequently has direct application-based questions — revise it carefully.
- Read the "Additional Information" boxes and timelines in NCERT chapters. Case-based questions in the board paper often draw from this content.
English
- Reading Comprehension carries 20 marks. Practice two unseen passages weekly from October onwards to build reading speed and vocabulary inference skills.
- Memorise the standard formats for formal letters, analytical paragraphs, and notices. Format adherence earns predictable marks.
- Know all prose chapters and poems from First Flight and Footprints Without Feet. Character sketch and theme-based questions of 3–4 marks each are common.
- Grammar questions (gap filling, editing, reordering) follow fixed patterns — revise active-passive voice, reported speech, and modals thoroughly.
Hindi
- Read all Sparsh prose chapters and Sanchayan stories. Questions on character behaviour, central ideas, and context from the text are directly asked.
- Write Hindi formal letters and paragraphs (nibandh) regularly — Section B tests these writing forms.
- Grammar (Vyakaran) carries 16 marks in Course A. Focus on Sandhi, Samas, Ras, and Alankar for the highest return per hour of study.
- Prepare bhavarth (explanation of meaning) for all Sparsh poems. A bhavarth question of 3–5 marks appears in almost every board paper.
CBSE Class 10 Syllabus 2027 FAQs
Ques. Is the CBSE Class 10 syllabus 2027 the same as last year?
Ans. The 2026–27 syllabus continues the rationalized curriculum from earlier sessions. Three Science chapters (Periodic Classification of Elements, Sustainable Management of Natural Resources, Sources of Energy) remain removed. CBSE released the 2026–27 official syllabus on April 2, 2026. Download the subject-wise PDFs from cbseacademic.nic.in to confirm any chapter-level changes.
Ques. Which subject has the highest weightage in the CBSE Class 10 board exam 2027?
Ans. All five core subjects carry equal total marks — 80 theory + 20 internal assessment = 100 marks each. Within subjects, Algebra is the highest-weightage unit (20 marks in Mathematics). In Science, Chemical Substances and World of Living are highest at 25 marks each. Preparing all five subjects equally is essential for a high aggregate.
Ques. Are NCERT textbooks enough for the CBSE Class 10 board exam 2027?
Ans. Yes, NCERT textbooks are sufficient as the primary source. All board exam questions are designed from NCERT content. After completing NCERT, use CBSE sample papers and one reference book per subject for additional practice. Do not replace NCERT with reference books — use reference books only to supplement it.
Ques. Where can I download the official CBSE Class 10 syllabus 2027 PDF?
Ans. You can download the official CBSE Class 10 syllabus 2027 PDF from cbseacademic.nic.in. Go to Curriculum → Secondary Curriculum (IX–X) → 2026–27. Separate subject-wise PDFs are available for Mathematics, Science, Social Science, English, and Hindi. These PDFs are the only authoritative source for the topic list and deleted content.
Ques. What are the most important chapters in Mathematics for CBSE Class 10 2027?
Ans. Algebra (Unit II) is the highest-weightage unit at 20 marks. Within it, Quadratic Equations, Pair of Linear Equations in Two Variables, and Arithmetic Progressions are most important. Geometry (Triangles and Circles, 15 marks) and Trigonometry (12 marks) follow. These three units account for 47 of the 80 theory marks.
Ques. Has the CBSE Class 10 Science syllabus been revised for 2027?
Ans. The Science syllabus for 2026–27 continues the rationalized version from earlier sessions. Three chapters remain removed: Periodic Classification of Elements, Sustainable Management of Natural Resources, and Sources of Energy. The assessed syllabus covers 13 chapters in five thematic units. Verify the final chapter list in the official 2026–27 Science syllabus PDF on cbseacademic.nic.in.
Ques. What is the difference between Mathematics Standard and Mathematics Basic in CBSE Class 10?
Ans. Both papers follow the same syllabus but differ in difficulty level. Mathematics Standard (Code 041) has more complex questions and is meant for students planning to study Mathematics in Class 11. Mathematics Basic (Code 241) has simpler questions and suits students who do not intend to continue with Mathematics. You select between them at the time of form submission.
Ques. How many chapters are in the CBSE Class 10 Social Science syllabus 2027?
Ans. The Social Science syllabus covers 25 chapters across four NCERT textbooks: 5 from History (India and the Contemporary World – II), 7 from Geography (Contemporary India – II), 8 from Political Science (Democratic Politics – II), and 5 from Economics (Understanding Economic Development). Each discipline carries equal marks (20 marks each) in the theory paper.
Ques. Is Evolution in the CBSE Class 10 Science syllabus for 2027?
Ans. The chapter "Heredity and Evolution" has been renamed "Heredity" in the rationalized syllabus. The Evolution section has been reduced in scope. Core Heredity concepts — Mendel’s laws, sex determination, genotype and phenotype — remain fully in the syllabus. Check the official CBSE 2026–27 Science syllabus PDF for the exact scope of the retained content.
Ques. What books should I follow for CBSE Class 10 Science 2027?
Ans. Start with NCERT Science Class 10 — it is the only source tested in the board exam. After completing NCERT, use Lakhmir Singh and Manjit Kaur (S. Chand) for Physics and Chemistry concept clarity. Use NCERT Exemplar Problems for higher-order thinking practice. Solve at least three CBSE sample papers before practical assessments in January 2027.
Ques. How should I cover the full CBSE Class 10 syllabus before the 2027 board exam?
Ans. With board exams in February–March 2027 and today being October 2026, you have four to five months. Divide this into four phases: October–November for completing all NCERT chapters; December for subject-wise revision and notes; January for practicals and CBSE sample paper practice; February for mock tests and weak-area revision. Prioritize high-weightage units first — Algebra in Maths, Chemical Substances and World of Living in Science.
Ques. What are competency-based questions in the CBSE Class 10 board exam 2027?
Ans. Competency-based questions test application, analysis, and evaluation rather than direct recall. They form 50% of the theory paper in the 2026–27 session. These questions present a real-life scenario or data set and ask you to apply concepts. Practicing CBSE sample papers and case-based question banks is the best way to prepare for this question type.
